A climber from Brighton has completed a series of gruelling challenges despite being told by doctors he would never walk again after breaking his back in a freak avalanche while snowboarding in 2008.

Paul Stewart has raised hundreds of thousands of pounds for charity by cycling, swimming and walking.

More recently, he climbed the mountain in France where his accident happened.
